VEHICLE- SPRING.

SPECIFICATION forming part of Letters Patent No. 692,613, dated February 4, 1902.

Application filed August 2, 1901.

To @ZZ w/wm it may concern/.5

Beit known that I, ZACHARIAH TQBUsH, a citizen of the United States,residin g at Grandledge, in the county of Eaton and State of Michigan, have invented a new and Improved Vehicle-Spring, of which the following is a specification.

My invention is an improvement in vehiclesprings, and has for an object to provide a simple novel construction by which to secure a considerable length of spring within a given space by forming scrolls at the ends and by leaving the center of the springs free, and also to provide a novel construction of springbar supporter at the center of the spring, as shown; and the invention consists in certain novel constructions and combination of parts, as will be hereinafter described and claimed.

In the drawings, Figure l is a perspective view of my spring. Fig. 2 is a top plan view thereof. Fig. 3 is a longitudinal section of the spring; and Fig. et is a detail perspective view, enlarged, showing the spring-bar supporter and the portions of the outside springs immediately connected therewith.

My spring is formed with the end springsY or bars A and the intermediate spring or bar B. Said springs are provided at their ends with returned portions a and b, which form eyes for the end bolts C, which connect the end springs and the intermediate spring, as shown in the drawings.

The end springs are bowed outwardly at their middles at A' and are also bowed reversely near their ends at A2, while the intermediate spring is bowed outwardly at B at its middle reversely to the portions A of the end springs, while its end portions B2 are bowed outwardly reversely to the intermediate portion B of the intermediate spring and the end portions.A2 of the end springs. By this construction I secu re a spring whose bars have a great length within a given space, in which the end springs and the intermediate spring cross each other at points between the center and outer ends of the springs and in which the end springs extend on opposite sides of the intermediate spring, as shown in the drawings. The spring-bar supporter D,

as best shown in Figs. 1, 2, and 4, includes the end bars E, which are secured between their Serial No. 70,611. (No modell!) ends to the end springs at E and are provided at their ends with the upwardly-turned por- `tions E2, forming the eyes for the bolts F, which unite the opposite plates E and secure ybetween them the connecting-plate G, which ticity of the springs,which are left free to operate elastically from end to` end, as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A vehicle-spring substantially as herein described consisting of the end springs, provided at their centers with the outwardlybowed portions and near their ends with the outwardly-bowed portions curved reversely to the said central portions, the intermediate spring arranged between the end springs and having at its center the outwardly-bowed portion arranged reversely to the center portions of the end springs, and 'provided at its ends with the outwardly-bowed portions which are arranged reversely to the end portions of the end springs, the devices connecting the ends of the end and intermediate springs, and the spring-bar supporter comprising the bars secured upon the end springs attheir centers,

and having the end eyes, the intermediate lbar arranged between said bars and provided at itsends with eyes, and the connectingbolts passing through the eyes of the said bars, .Y

all substantially as and for the purposes set forth.

2. The combination in a vehicle-spring of the intermediate spring, the end springs bowed outwardly at their middles, and the spring-bar supporter consisting of the bars secured between their ends to the end springs, the bar intermediate the said end spring-bars, and devices connecting the said bars at their ends, substantially as set forth.

3. In a vehicle-spring the combination of the end springs, the intermediate spring, said IOO end and intermediate springs ben bowed and the bolts passing' through said eyes, suboutwztrdly at their middles in reverse direestftntftlly as and for the purpose set forth.

tions, the bars secured at their middles upon y r Y y the outwardly-bowed portions of the end l ACHARIAH l' BUSH' springs and provided with the end eyes, the l Witnesses:

bal' between the said bars and having the end W. R. CLARKE, eyes coinciding with those of the end bars, R. A. LATTING.
